RECORDING MECHANISM.

Specification of Letters Patent.

Patented lllarch so, 1909.

Application filed September 19, 1908. Serial No. 453,789.

'1 all whom 'it may concern:

Be it known that 1, WILLIAM H. PIKE, Jr., a citizen of the United States, formerly residing at Orange, New Jersey, now residing at London, England, have invented certain new and useful Improvements in Recording Mechanism, of which the following is a specification.

My invention relates to recording apparatus which, while adapted for use with different styles of recorders, is especially adapted for use with adding machines such, for instance, as that patented to me June 28, 1904, No. 763,692, and my invention consists in certain means for controllin the actioniof the hammers or strikers, or 0t er devices, for acting upon type supported by movable carriers, as fully'set forth hereinafter and as illustrated in the accompanying drawing, in which: i

Figure 1 isan elevation of a recording apparatus embodying my improvement and showing it in connection with such parts of an adding machine as is necessary to enable its application to adders to be understood; Fig. 2 is a front view looking inthe direction of the arrow, Fig. 1.

The type carriers G may be of an suitable construction and support movab e type a, which, by the movements of the carriers, may be brought above a platen X, and those which are in printing line will be struck by hammers F, undenwhich term I include any kind of device which is the means of causin the type inprinting line to make the desire Impression.

As shown there is a series of hammers F mounted upon a cross-shaft 4 and combined with suitable actuating means, as a springf, which tend to throw the hammers against the type, and a retainer Kis set inposition to engage shoulders of the hammers to hold them out of operating position. The retainer K is operated from a working shaft V, so as to release the hammers after the carriers G have been set in printing position.

As shown the carriers are moved in one direction'each by a sprin 400 connected to a slide 400 pivoted to the ower ends of the carriers, and are restored to normal inoperative position b the action of a restorin cam 900;

of the shalt carrier is moved is determined by stops 430'- -.-on the strips 400, making contact with "the.

V, and the extent to w I 'ch each" that the depression of any key having a figure thereon will permit the carrier to be moved to a position to bring the. type imprinting said figure in printing line opposite ."the platen X.

There are swinging arms 205, one to each strip 400, in position to contact with one of the stops 430, and on depressing any key of a series the arm 205, connected with that series is swung by a shoulder upon the key stem bearing upon an arm 207 on a-shaft 215, supporting the arm 205, thereby carrying the latter out of position, and the arms 205 that are not thus carried out of position, where no key. of a series is set, will limit the movement of the coacting strip 400 so that as the cam. 900 rises the associated type carrier can move to a position to bring a cipher type into printing line. This insures the prmting of ciphers wherever the keys are not operated to carry the carriers to position to print figures, under which term I include to print the ciphers at the left of the figures constituting any number or item to be printed, and in order to avoid the printing of ci hers at these points I provide a detent whic may be progressively shifted into posivent' them from operating upon, the type, which detent is automatically shifted so as to occupy a position to obstruct the movements carriers at the. left of those which are set n position to rint figures. The said detent may be di' erently constructed and operated so as to be shifted to a ositionto obstruct the movement of all of t e hammers at the left of those which are to be operated to rint the item, but, as shown, the detent is and a traversing movement successively past the hammers is suitably imparted to the said detent at each 0 eration of the rockshaft V.. As shown t is movement is imparted by means of a bell crank lever B, the one arm of the lever entering an opening in the slide and the other arm resting upon a lever A pivoted at 8 to the frame of the machine and having a roller 10 adapted to bear ii on a cam I upon the shaft V, which cam ellivates the lever A and swings the lever B in the direction of its arrow, as the working shaft is rocked in the direction of its arrow stems of keys 201, thepartsbeing so arranged to restore the parts to normal position.-

tion to contact with the hammers and preof those hammers which coact with the type the nine integers. It is however undesirable 1n the form of a slide D having a wing'E,

' When the working shaft is rocked in the opposite direction a spring 12, connected with the lever B, will swing the latter and move the slide D to the extent determined by one of a series of stops 0. These stops may be of any suitable character but as shown consist of arms projecting from the rock-shaft 2 -swung in one direction by a spring 13, an-

other arm 14 from said shaft projecting over a stud 9 at the side of the adjacent carrier G.

These parts are so arranged that when a carrier is in its normal retracted position the detent arm. C will be out of position to coact with the wing E of the detent D, but when 15 any carrier is set far enough toward the platen to bring a type that will print a figure into printing line, the contact of the stud 9, with a shoulder of the arm 14, will swing the arm upward and rock the shaft 2 so as to bring the stop arm 0 in position to prevent the detent D from sliding past the sto arm C, and therefore the said detent wi not affect the movement of the hammers coacting with the carrier thus set forward, nor can it move to a position to prevent the movements of any of the hammers at the right, while the hammers at the left will all be obstructed by their contact With the detent even after they are released by the shifting of the retainer K. The parts are so constructed and arranged however that this shifting of the retainer which releases all the hammers does not take place until the detent has been set in position, and the various carriers have been set in position, to bring their proper ty e to printing line.

After t e desired imprint has been made, an arm J upon 'the working shaft V will make contact with a stud upon a rocking 40 shaft H, having at the top a cross-bar l6 which is thus brought against the under edges of the hammers and restores the same to such a position'that the retainer K can engage the shoulders thereof, and can hold them out of action.

Any suitable means may be employed for imparting movement to the retainer K after the arts have been properly set in position. As s own a stud upon an arm carried by the rocking shaft may 0 erate upon a lever connected by a link'with an arm upon the shaft of the retainer K, a 5 ring serving to. swing the latter toward the hammers.
